Authorities have confirmed the identity of a body found in the Delaware River Saturday near Trenton as a kayaker who went missing on June 14 in the Lackawaxen River, a tributary of the Delaware.

Waterways Conservation Officer Robert Plumb of the Pennsylvania Fish & Boat Commission said medical examiners from Morris County, N.J. identified the victim as Shawn Martin, 29, of Beach Lake. Martin was kayaking with a friend when his boat flipped and he entered the river around Kimbles Bridge near Hawley.

At the time, the river had been swollen from overnight rain, Plumb said.

Martin’s unsecured life jacket slipped off him as he fell into the river, the officer said. Both the life jacket and kayak were recovered some 10 miles downstream from the point where he entered the water.

Martin’s body had traveled about 80 to 90 miles over a period of six weeks. His body was found Saturday evening on Duck Island near Trenton, N.J.

Earlier that same day, Daven Harrison, 20, went missing in the Delaware around Knight’s Eddy in Lumberland, N.Y. The discovery of Martin’s body near Trenton caused some initial confusion in reports about Harrison’s disappearance.

Harrison’s body was found Monday afternoon a short distance downstream from where he had been last seen, according to the National Park Service.

National Park rangers were reluctant to release Martin’s identity before medical examiners completed their analysis. Officials identified him Monday morning through tattoos on his body, Plumb said.
